Chemoimmunotherapy Plus Residual Lesion Irradiation for the Treatment of Extensive Stage Small-cell Lung Cancer

Summary

This is a phase II trial studies the effect of chemoimmunotherapy sequential residual tumor irradiation in treating patients with extensive stage small cell lung cancer. Even though small cell lung cancer is initially highly responsive to first-line chemotherapy plus PD-L1 inhibitors, treatment resistance inevitably happens. Residual tumor irradiation my prolong drug resistance, and may help prevent the growth and spread of the tumor cells to other parts of the body.

Eligibility

Inclusion Criteria:

\>= 18 years of age Have an Eastern Cooperative Oncology Group (ECOG) performance status of =\< 1 at the time of study treatment initiation Histologically or cytologically confirmed diagnosis of small cell lung cancer (SCLC) Patient should have extensive stage disease, defined as, malignant pleural effusion, pulmonary metastases in the contralateral lung, and/or the presence of extra-thoracic metastatic disease Must have measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 prior to starting platinum-based systemic chemotherapy Absolute neutrophil count (ANC) \>= 1.5 x 10\^9/L Platelets \>= 100 x 10\^9/L Hemoglobin \>= 9 g/dL Serum creatinine =\< 1.5 x institution upper limit of normal (ULN) and calculated creatinine clearance of at least 15 ml/min.

Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =\< 3 x upper limit of normal (ULN) (ALT and AST =\< 5 x ULN is acceptable if liver metastases are present) Total serum bilirubin =\< 1.5 x ULN. For patients with well documented Gilbert's syndrome, total bilirubin =\< 3 x ULN with direct bilirubin within normal range.

Participant must understand the investigational nature of this study and sign an approved written informed consent form prior to receiving any study related procedure.

Exclusion Criteria:

* ad major surgery within 14 days prior to starting study drug or has not recovered from major side effects (tumor biopsy is not considered major surgery) resulting from a prior surgery Positive for immunosuppressive disease, acquired immunodeficiency syndrome (AIDS) or other immune depressing diseases. For human immunodeficiency virus (HIV), HVC and HBC-mandatory testing is required prior to enrollment Patient has known hypersensitivity to the components of the study drugs or any analogs History or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate, including, but not limited to: Myocardial infarction or arterial or venous thromboembolic events within 6 months prior to baseline or severe or unstable angina, New York Heart Association (NYHA) class III or IV disease. History of documented congestive heart failure (New York Heart Association functional classification III or IV) within 6 months prior to baseline. Poorly controlled arrhythmias
